[AusNOG] Old route from PIPE NSW

[Bruce Forster]

Not sure what version of hardware and what software version you are running
but in some older versions of Cisco IOS i have seen stale routes hanging
about.

In the eg im taking about, You have a cluster of router reflectors and one
seems to hang onto old stale route and the others are fine.. After the
session's are cleared it seems update.
